Answer provided by our tutors
let
x = the money invested at 3%
y = the money invested at 4%
the total money invested is Rs.45,000
x + y = 45000
twice as much being invested at 3 percent as 4 percent.
x = 2y
his total amount interest return is Rs. 1,500
0.03*x + 0.04*y = 1500
by solving the system
x + y = 45000
x = 2y
0.03*x + 0.04*y = 1500
we find
x = Rs 30,000
y = Rs 15,000
Mr. Altaf have invested Rs 30,000 at 3% and Rs 15,000 at 4%.
